I found today solution on ati proprietary driver which actually works. I have HP pavilion g7 notebook with hybrid ati/intel graphic and till today I had problem running ati proprietary driver while X server was crashing with segmentation fault. This is my system:

This works great on my Hp ProBook 4730s with Intel HD 3000 / ATI Radeon HD 6490M hybrid.But i got one problem....

When install Adobe Flash downloaded from their site, and installed it as it described in readme... after restart Xserver cannot be started... what could be the problem?

EDIT: I try first to update Adobe Flash to latest version, and after that installed ATI driver, but than when i run sudo aticonfig --initial -f, it says it cannot make xorg.conf file for discrete graphic card.

After that i make fresh install of Mint 14, and i didn't upgrade Flash and everything works great.Switching from Radeon to Intel graphic card is working from Calayst Control Center

That didn't work for me. I've reinstalled LM 14 6 times, but it results into broken Xserver. One of the times, AMDCCC was working well; but of curiosity of how I did it so easily, I re-installed LM 14. And next time it didn't work.
